Single-Phase AC Voltage Regulator Implementation for Enhancing Transformer Efficiency in Rural Community Electrification Programs

Abstract

The stability of voltage supply is a critical requirement in delivering reliable power sources, especially in rural electrification systems aimed at improving community well-being. Ensuring a constant voltage within electrical circuits is crucial, as voltage fluctuations during transmission can cause significant issues. These fluctuations, often resulting from voltage drops in distribution networks, can lead to reduced lifespan and performance of electronic devices in households and industries. Several factors influence voltage stability, including increased transmission line loading, limitations in reactive power regulation, dynamic adjustments in load-tap-changing transformers, and load characteristics. This study explores the development of a single-phase AC voltage regulator designed to enhance transformer efficiency, particularly in rural electrification programs. Using PSIM software, a voltage regulation circuit was developed, incorporating key components such as thyristors, transformers, Silicon-Controlled Rectifiers (SCRs), and other auxiliary elements. The results of this research contribute to the design of robust and sustainable electrification solutions, addressing the specific needs of underserved rural communities.
